🚨 Tiny Tech Taps Seawater to Power Up Researchers have designed a nanoscale device that can generate electricity from the natural salt gradient where seawater meets freshwater. The device is made of semiconductor materials and utilizes "Coulomb drag" - the interactions between flowing salt ions and charges in the device - to produce voltage and current. In simulations, the researchers found the device works equally well with attractive or repulsive electric forces between the ions and device charges. Additionally, both positive and negative ion flows can create momentum transfer and current amplification, boosting power output. The simple and versatile design means the effect does not depend on specific channel shapes or materials. The team believes arrays of the devices could match or exceed solar power density. While still conceptual, this nano-generator's ability to tap into saltwater gradients makes it a promising potential new source of renewable energy. River mouths and other coastal areas could see a future "blue energy" revolution from emerging tech like this. #SRED #RD #Funding #Innovation #Grants #TaxCredits #CleanEnergy #JonIrwin https://lnkd.in/g5pVuuKK

"Discover the Whole World of Electronics with our Blog 👓📕🤓" 🔴How to Design Gate Drivers for SiC MOSFETs Silicon carbide (SiC) power semiconductors that operate at switching frequencies above 100kHz are becoming much more prevalent in trending areas like E-mobility, renewable energy, or industrial drives. Their extremely fast switching speed helps to achieve higher efficiency, smaller size and lower system cost, especially in high-voltage, high-power applications. In correlation, this means gate-drive requirements are becoming more sophisticated. This can be a challenge as the desire for more compact, efficient and flexible power supplies are wanted. Würth Elektronik has the solution. Supplemented by a controller from Analog Devices, the key component of the design is the new WE-AGDT transformer. 📲 Read more here: https://we-online.link/xu 📢Check out our WE-AGDT Auxiliary Gate Drive Transformer Product: https://we-online.link/xt #Blog #ElectronicsInsight #GateDriveTransformer #AGDT

Optoelectronic materials convert light into electricity and vice versa. When light strikes an OEM, its energy is absorbed by electrons in the crystal lattice. The electrons that absorb this energy jump from the low-energy valence band to the high-energy conduction band, crossing the energy gap.

Do you believe it is sexy to think about whether current flows horizontally “along” a chip or vertically through it? 🤔 ➡ ⬇ ❓ If your answer is no, maybe you should. After all, our German Federal President seems to thinks so – because MOSFETS (= semiconductor-based electrical switches) with purely vertical channels are much more energy-efficient. The President’s team has nominated a new technology developed by colleagues of mine at Infineon Technologies for his prestigious national award “Deutscher Zukunftspreis”. 🏅 Together with Chemnitz University of Technology, they have developed the world’s first silicon carbide MOSFET with a vertical channel and innovative copper contacting for high voltage of 3300V. 🤓 Sounds like nerdy tech talk to you? Here’s an example why this is so cool even beyond the engineering bubble: Put into action in one electric train, this can save around 300 MWh of electricity per year – roughly what 100 single-family homes consume in the same timeframe. Plus: Trains become less noisy. Great news for people who live near the tracks. 🚆 🏡 🤫 Keeping my fingers crossed for Konrad Schraml and Caspar Leendertz and their team for the final award decision on November 27.

Ambient Photonics solar cells stand out for two primary reasons. The first is that they have a significantly higher power density compared to traditional indoor solar cells. The second reason is that their production costs are in line with what manufacturers of devices are willing to pay.

**Embracing Efficiency with SiC Hybrid Modules** Industries are pushing for greater efficiency and compact solutions, and SiC (Silicon Carbide) hybrid modules are at the forefront of this evolution! The outstanding characteristics of SiC devices, especially in high-temperature operation and breakdown voltage capabilities, are setting new standards in power electronics. 🚀 The innovative combination of Si-IGBT chips with SiC-SBD (Schottky Barrier Diode) chips offers numerous advantages over traditional Si modules: 1️⃣ **Enhanced Reverse Recovery Characteristics**: SiC-SBD's unipolar nature results in minimal reverse recovery operation, significantly reducing losses compared to traditional FRED diodes. 2️⃣ **Lower Turn-On Losses**: Our SiC hybrid modules feature turn-on losses that are about 40% lower than Si devices, allowing for more efficient energy management and a longer operational lifespan. 3️⃣ **Reduced Turn-Off Surges**: By ensuring equal device characteristics for IGBT and the main circuit’s inductance, our SiC modules minimize transient voltages, leading to significantly suppressed surge voltages during turn-off and reduced turn-off losses. The integration of SiC technology not only promises enhanced efficiency but also facilitates equipment downsizing, paving the way for more sustainable solutions across various industries. 📣 I’m eager to connect with fellow professionals and industry experts who are enthusiastic about advancing power electronics. Let’s start a conversation about best practices and innovations in this dynamic space! #SiC #HybridModules #PowerElectronics #Efficiency #Innovation #Sustainability

I am excited to share that our research paper, titled "Expandable Three-Port DC-DC Converter With Notable Properties and Without Effective Limitations Suitable for Off-Grid Applications," has been published in the esteemed IEEE Transactions on Power Electronics. Access the paper via this link: https://lnkd.in/d9rjMTtB I want to express my sincere gratitude to my esteemed colleagues,Dr. Vahid Abbasi and Dr. Siroos Hemmati from Kermanshah University of Technology. Their invaluable contributions and steadfast support were crucial to the success of our research project. Abstract: A new expandable, nonisolated, high step-up three-port dc–dc converter (TPC), with two inputs and one output, which includes a bidirectional port for charging and discharging energy storage, is presented in this article. The proposed TPC is compatible with expanding the number of inputs and becoming a multi-input converter (MIC). Also, it has a high voltage gain, an appropriate number of components, low voltage stress on the semiconductors, and low input current ripple. In addition, this article includes new kinds of comparison criteria to assess MICs from various perspectives, such as performance limitations and quality. The design of the converter incorporates beneficial characteristics, such as continuous input current and a common ground between the energy sources and the load. It also has the capability to operate in battery-alone mode and under unbalanced conditions, accommodating different powers and voltage levels of the input sources. Moreover, the employed switching strategy enables effective control over the input current of the sources as well as the output voltage. Various operating modes and steady-state analysis have been discussed to validate the advantages of the proposed TPC. Finally, a 300-W laboratory prototype is designed to verify the performance of the proposed TPC under sudden changes and during mode transitions. #PowerElectronics #Converters #IEEE #TPE #RenewableEnergy #KUT
